Answer:

so basically just solve all the equations by the letters and the answers will be the letters so like you would do 20 divided by 4 and the answer would be 5 so anything that is 5 down below would be F

Suppose that 10 sophomores, 3 juniors, and 10 seniors are candidates for a prestigious mathematics award of which three will be

faltersainse [42]

Answer:

1771 possible ways

Step-by-step explanation:

In this case, we need to know first how many candidates are in total:

10 + 3 + 10 = 23 candidates in total.

Now, we need to choose 3 of them to receive an award. In this case, we have several scenarios, but as it's an award we can also assume that the order in which the candidates are chosen do not matter, so, the formula to use is the following:

C = m! / n! (m - n)!

Where m is the total candidates and n, is the number of candidates to be chosen. Replacing this data we have:

C = 23! / 3! (23 - 3)!

C = 2.59x10^22 / 6(2.43x10^18)

C = 1771

So we have 1771 ways of choose the candidates.

A bag contains 8 blue marbles, 6 green marbles, 12 yellow marbles, and 10 orange marbles. A marble is drawn at random from the b

VladimirAG [237]

Total Marbles = 8 + 6 + 12 + 10 = 36

Probability the marble is blue = 8/36

Inverse this to get the probability of the marble not being blue

Probability of the marble not being blue = 28/36 = 7/9
